Who knows - anything is possible!!!
A couple of years ago I phoned Carmichael Estates who own the property in that area to ask if I could look at their archives to see what what they had for John Baillie but was told that they weren't archived or available to the public.
It's a long time this I looked at this but I thought that John Baillie's wife may have been Grizel Mathison daughter of James Mathison & Janet Robison born at Braecroft on 24 Feb 1792 in the parish of Troqueer.
You've renewed my interest in the Baillies & Matthewisons (all variants included) & at least they have some immortality as I always think about them when I drive over Hyndford Bridge!!!
